Product details

Siemens SENTRON 3VA2340-5JP32-0AD0 — 400 A MCCB with Communication

Interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, and 75.6 kA at 500 V — covering most industrial distribution and motor branch circuits.

Continuous current holds at 400 A from 40 °C up to 50 °C, then derates linearly: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. Maximum power loss is 96 W at rated load. Panel builders should account for this heat dissipation in enclosure sizing — the 96 W is not trivial in a sealed cabinet.

Mounting Dimensions and Panel Fit

Verify that the existing panel has at least 110 mm clearance behind the mounting plane for the case depth and wiring bends.
